Thermal printing head and method of manufacturing the same.

摘要

A laminated wiring conductor layer of a thermal printing head consists of common wiring (50) connected to one end of a patterned heating resistor layer, and individual wirings (30) connected to the other end of the patterned heating resistor layer (21). The individual wirings (30) are separated from the common wiring (50) by a predetermined interval. The laminated wiring conductor layer includes a plurality of conductor layers in which a first conductor layer exhibits excellent bonding to the heating resistor layer and cannot be readily soldered and hence prevents flow of a solder while a second conductor layer laminated on the first layer is easily soldered and less corrosive than aluminum. <IMAGE>
